Dear Mr. Aucbter:
.
It is widely recognized that exposure to asbestos fibers can be
a significant source of risk to American workers. There is no
known threshold for "safe" exposure to asbestos. Also, there
are convincing data and research studies that document the na-
ture of the risk associated with such exposure. Organization
Resources Counselors, Inc. (ORC) thinks that the present standard
of two fibers per cubic centimeter is inadequate to protect
workers and that prompt consideration is needed to reevaluate
the existing standard. OSHA needs to reconsider the permissible
exposure limits and other criteria in accordance with current
state-of-the-art knowledge of the risk associated with exposure '
to asbestos.
.
.
ORC is recommending an eight hour time weighted average airborne
concentration not to exceed 0.5 fibers per cubic centimeter.
ORC further recommends that for most of general industry,
compliance be achieved over a period of.12 months from the
effective date of the standard and that the asbestos producing
and manufacturingindustriesreduce permissible exposure limits
to one fiber per cubic centimeter^within one year and to 0.5
fibers per cubic centimeter within four years- The bases for
.
these recommendations and other suggested criteria are included
in the attached ORC recommended standard- The ORC position is
submitted recognizing that other countries, organizations, and
individuals have different opinions and recommendations regarding
this most complex subject. I encourage you to carefully consider
all information submitted to OSHA.
. The ORC recommended exposure limits take into consideration the
difficult problemsassociated with the monitoring,collection,
. and analysis of airborne levels of asbestos. In reaching its

decision. OSHA must take into account that the difficulty of
monitoring and measuring the amount of airborne asbestos im
pacts significantly on the integrity of the'permissible exposure
limit. Also, the final limit selected by OSHA (within reasonable
limits, say 0.5 or 0.1 fibers per cubic centimeter) will not
-
significantly alter the actual level of protection provided ' ' ' '
to American workers. ,

ORC is also concerned about the lack of adequate testing and
certification of respirators worn by workers exposed to asbestos
fibers. While our recommendations emphasize the importance of .
having a fully integrated program to deal with asbestos in the~ =
workplace, respirators must inevitably be used in a large
'
number of workplaces to protect employees against exposure to- V
airborne asbestos fibers

In conclusion, ORC applaudes OSHA's efforts to strengthen its
in
asbestos standard. ORC is submitting recommendations, which represent the opinions of ORC only, as an aid to OSHA so that
it can reach reasonable and responsible decisions on this real and complex' issue.
_
sincerely yours.
